PROBLEM TO BE SOLVED: To provide a switchable magnetic device for fixing a form device on form support material capable of being magnetized. SOLUTION: The magnetic device comprises a magnetic means for generating magnetic force, and a support means capable of being at least sectionally magnetized for at least indirectly supporting the magnetic means on the form support material when the magnetic device is installed on the form support material. Also, the magnetic device is switchable between a first position where the support means transmits the magnetic force to the form support material, and fixes the magnetic device on the form support material, and a second position where transmission of the magnetic force between the magnetic means and the form support material are substantially blocked, and the magnetic device is removable from the form support material.
